 # May 17, 2017
 # Updated Dec. 22, 2018 to accomodate in-lined standard cell subcircuits
 # (i.e., not from a .include statement) and corrected duplicate .end statement.
+# Updated Jan. 12, 2024 to fix port direction when inputs and outputs are not
+# buffered, and a subcircuit output signal is also fed back to other gates in
+# the subcircuit.
